Someone has probably already thought of this and posted, but just in case - the iPad version of Dorico is a potential game changer for the way chorus members learn their parts.
My spouse (a wonderful singer but just learning to read music) has joined our community chorus, and to help her learn the soprano parts, I’ve been inputting the vocal parts for Poulenc’s Gloria. Having the ability to tap on a note and hear it, as well as listen to playback of some or all voices, change the playback sound, tempo, etc. etc. is really just amazing.
It makes the iPad version of Dorico even more useful than I imagined.
